__Visual and Biological Survey__
The observed wildlife at the Long Island Creek 6A study area consisted of waterfowl, amphibians fish, and insects. There were a fair amount small fish, some medium sized fish, and quite a few tadpoles in this portion of Long Island Creek. There was one fallen tree, which built up quite a bit of debris on the upstream side, and was blocking the movement of the water and fish. There was a heavy coating of both brown and green algae in this section of the creek. Despite the variety and relatively large amount of trees, about 70% of the water was totally exposed to direct sunlight.

__Tree Risk Assessment__
Group six conducted an urban ecology study of site 6 on Long Island Creek within the East Palisades Chattahoochee River National Recreation Area. Site 6 consists of two separate locations, site A and Site B. At site A, we conducted a risk assessment on 10 different trees within our area of study using the USDA Community Tree Evaluation Form. Trees 1-5 are on the right bank and trees 6-10 are on the left bank as you look up stream. The follow chart shows the trees in trees and the risks that we calculated:

__Results__
This chart shows all trees 10 trees we selected for this risk assessment along with the defect codes. This risk assessment notes that site 6A has a higher number of the Yellow Poplar Trees (LITU) at this location with half of the trees selected is this species. The trees at this site have a lower level of risk because of their location within the protected area of the NPS. Tree 6, the dead tree in the risk assessment may need to be monitored because of the recreational activities that occur at the park. Overall the trees at site 6A are in relatively good shape and should be left alone to grow naturally of their location in the protected forest.
